I've implemented optimistic and pessimistic validation for the particle swarm searches now as well (as opposed to just the differential evolution searches that were running before). I've tested them quite a bit so I think it's working correctly, but just warning you the server might crash a few times in the next few days while I get all the bugs sorted out.

Let me know if you're having any problems with the ps_s222_opt_1, ps_s222_pes_1 workunits.

On my 4870 I'm seeing about a 13% increase in crunch time (for the same credit) and what's interesting on my 4850 I'm only seeing about a 2% increase in crunch time.

My 4830 is still running the same times from what I can tell.

304 to 308 seconds.

My 4770s are taking about 30% longer for the pes WUs, the opt WUs take the same time as the old WUs.

There really shouldn't be any difference in compute time. The only changes were server-side.

Times were definitely longer initially, but on looking at them now they have gone back to 'normal'.

[edit] Sort of, the last one on my 4870 was 18 seconds longer (10%), so I'm seeing them move around a bit.
